What is in space, what is in air, what is in fire, what is in brilliance, what is in fame, oh Naciketas.

Yama continues his enumeration of gifts, now encompassing cosmic elements and brilliant qualities. The verse lists: antarikṣa (space, heaven), vāyu (air/wind), tejas (fire/radiance), yaśas (fame, glory). These are the great elements and attributes that constitute the manifested universe and spiritual reputation.

The structure of the verse is poetic: four times the particle yad (what) followed by locatives, creating a rhythm of accumulation. Each successive element is more subtle and powerful than the previous: space contains air, air feeds fire, fire produces radiance, and radiance generates fame.

The implicit offer is of dominion over these elements or participation in their nature. In the Vedic tradition, great sages could control the elements through accumulated tapas. Yama offers Naciketas these cosmic powers as compensation for abandoning his question about death.

Naciketas’s implicit response — not explicitly expressed but understood from the context — is that even these great elements are anitya (impermanent). Space itself is a product of cosmic evolution and will eventually dissolve. Only the Ātman is nitya (eternal). Naciketas rejects even cosmic control for the knowledge of the cosmic controller.
